Support interfaces with MTU > 1500
Suricata currently doesn't support interfaces with MTU set under 1500.
the default block size is 32768 on most machines (pagesize ^ order --> 4096 ^ 3),
thus suricata splits the payload to 32768 / 1500 -> 22.
If an interface has a bigger MTU, such as localhost which defaults to 65536, the block size is too small.
